Constructed in 1938 to defend San Francisco from enemy battleships, Battery Davis once house a huge cannon. Similar batteries dotted the Pacific shore, many of them with "disappearing guns," which were loaded and aimed while lying behind a wall, then popped up, fired, and immediately dropped below the wall, hopefully before the enemy could get a bead on them.
Of course, as WWII proved, battleships were no longer the major naval threat to cities, having been replaced by aircraft carriers, which would never have sailed within range of coastal cannons. All the batteries were dismantled after the war.
